Abstract:
This disclosure provides systems, methods, and apparatus for supporting a bezel region of a display device. A display device can include a first substrate and a second substrate coupled by an edge seal. An array of shutter-based display elements can be positioned within an image forming region between the first and second substrates. A plurality of mechanical supports can be positioned within a bezel region outside of the image-rendering region and within the edge seal. Along a side of the bezel region that extends in a direction perpendicular to a direction of shutter motion, adjacent mechanical supports can be separated from one another by a gap that is longer than each of the mechanical supports in the direction perpendicular to the direction of shutter motion.

Abstract:
A high efficiency, long life, video rate, electrophoretic display comprises fluid containing sub-pixel structures that are periodic, and aligned with a color filter array. A fluid comprising of electrophoretically mobile particles is compartmentalized at the size scale of the individual filters (one per filter) such that the particles may be moved to either allow light to be returned through the same filter back towards the viewer by total internal reflection (TIR) or conventional reflection to create a light state or to be absorbed by the particles to create a dark state. High reflectance is achieved through the use of structures that avoid ITO layers in the light path and reflecting most light, by virtue of a dual control of light by TIR and transmission to a reflector. In one embodiment the structures are in the shape of truncated pyramids.
Abstract:
This disclosure provides systems, methods and apparatus for a shutter-based light modulator. The shutter includes at least three depressions extending outward from the surface of the shutter. Any two adjacent depressions of the at least three depressions define a gap therebetween to reduce damping forces caused by fluids in which the shutter is immersed. In some implementations, the at least three depressions can be aligned into more than one row, each row including more than two of the at least three depressions, along the surface of the shutter. In some implementations, to improve structural stability of the shutter, depressions in one row are staggered with respect to depressions in another row.
Abstract:
This disclosure provides systems, methods and apparatus for displaying images. A display apparatus includes display elements formed on a transparent substrate. An elevated aperture layer (EAL) is fabricated over the display elements. An opposing substrate is coupled to the transparent substrate, with the display elements and the EAL positioned between the two substrates. To prevent the opposing substrate from coming into contact with the EAL and potentially damaging the EAL or the display elements, a spacer is built from the same materials used to form the display elements and the EAL. The spacer extends to a distance above the transparent substrate beyond upper surface of the EAL and encapsulates layers of polymer material used in creating a mold for the EAL.
Abstract:
This disclosure provides systems, methods and apparatus for modulating light to form an image on a display, as well as methods manufacturing such apparatus. The display apparatus includes dual-level shutter assemblies. Each dual-level shutter assembly includes front and rear light obstructing levels positioned adjacent to respective front and rear light blocking layers. The front and rear light blocking layers define apertures providing optical paths from a backlight to the front of the display. The dual-level shutters selectively obstruct these optical paths to generate an image.
Abstract:
An insulated glazing unit (100) includes a spacer (150) defining a framed area, first and second glazing panes (320) attached to the spacer (150), a pane conductive layer (322) on an inner surface of the first glazing pane (320), and a dielectric layer (324) disposed on the pane conductive layer (322). A shade (310) for use with the insulated glazing unit (100) is affixed to the first glazing pane (320). The shade (310) includes one or more layers selected from a resilient layer (316), a substantially transparent shade conductive layer (318), and an opaque shade conductive layer (325). When an electric drive is applied between the pane conductive layer (322) and the shade conductive layer (318, 325), a potential difference between the pane conductive layer (322) and the shade conductive layer (318, 325) causes the shade (310) to extend from a retracted configuration to an extended configuration. The shade (310) can further include at least one ink coating layer (340) including pigments that selectively reflect or absorb certain visible colors and infrared.
Abstract:
This disclosure provides systems, methods and apparatus for forming display structures having shutters that have a different height than corresponding actuators. In one aspect, a display apparatus includes an electrostatic actuator including opposing beam electrodes having primary faces normal to a substrate on which they are formed. The height of at least one of the opposing beam electrodes defines an actuator height. The apparatus also includes a shutter configured to be driven by the electrostatic actuator. The shutter includes at least one protrusion, the protrusion having a first sidewall and a second sidewall normal to a primary plane of the shutter, wherein a first sidewall height of the first sidewall is substantially different from the actuator height.
